well, you can't be that picky if you're looking to buy used.  lulz.    those wheels are the spyder wheels--they don't come on the early z-06's, which is what your budget dictates.    black was available all years iirc, jetstream blue (was my second choice), was not available until 2008.  you won't find a low mileage (assuming less than 10k miles) for $40k.   
  good luck bro
